Export information about static libraries, shared libraries and exported flags through Providers instead of accessing the module directly. Much more is left to be converted, but this significantly simplifies the dependencies on libraries with stubs by making it easy for a module to masquerade as another by simply exporting the providers from the other module. Instead of depending on all the versions of a library and then picking which one to use later, it can depend only on the implementation variant and then select the right SharedLibraryInfo from the variant. Test: m checkbuild Test: only expected changes to build.ninja Change-Id: I1fd9eb4d251cf96ed8398d586efc3e0817663c76
